Abstract

The quasar 3C 279 is one of the best-studied flat spectrum radio quasars. It is located at a comparatively large redshift of z = 0.536: E > 100 GeV observations of such distant sources were until recently impossible both due to the expected steep energy spectrum and the expected attenuation of the γ-rays by the extragalactic background light. Here we present results on the observation of 3C 279 with the MAGIC telescope in early 2006. We report the detection of a significant very high energy γ-ray signal in the MAGIC energy range on the observation night of 2006 February 23.
